Rare black rhino born at Sioux Falls zoo

The Great Plains Zoo in Sioux Falls has announced the birth of a rare rhinoceros.

The Zoo's 13-year-old eastern black rhino "Imara" recently gave birth to her second calf, a male weighing 92 pounds.

Black rhinos, native to Africa, are the most endangered of the five rhino species, with fewer than 4,000 in the world.

Zoo officials say the calf will spend much of his time sleeping, eating and settling in with his mother. The calf is expected to be on exhibit in the rhino day room, viewable by the public, in the next several weeks.
